Could time travel remove itself?

Do all time travelers drive a DeLorean? Seems unlikely, although it was cool.

I doubt that time travel could ever really happen. But some scientists like to ponder it, and I agree it can be interesting to think about. There are many paradoxes that it creates. A new hypothesis is that if time travel ever gets invented, that it would create its own destruction by introducing instability into certain realities which would eventually lead to the most stable possible timeline — that is, one without time travel at all.

It’s true that time travel would definitely create instabilities. People would go through history and wreck it, whether for their personal gain or just for fun or to be malicious or even without trying to. Facts and historical events would get altered, which would change the future. But with multiple people changing the past, they could create a future that cannot exist due to being incompatible with itself. The universe automatically makes things be in balance. We’ve defined this as the laws of thermodynamics. Objects will return to their most stable state, to keep equilibrium. So by that reasoning, it’s possible that even if time travel were to exist, it might lead to a future where it cannot exist. That leads to a paradox which might make your brain hurt if you try to understand it. 🙂 If it removed itself, would we forget about it and keep reinventing it? Wouldn’t that cause some distortions in the time-space continuum? What if someone somehow created a future that required time travel to exist? Would our universe just go poof?

BTW, the article linked above is called “Where Are All the Tourists From 3025?”, which seems like a good title for a book…

Bonus: Time travel becoming confusing reminds me of several episodes of Milo Murphy’s Law, which is an awesome show if you don’t know. Don’t think it’s just a kid’s show because it’s animated. It’s clean and family-friendly, but hilarious and full of parody references and inside jokes. And the lead character is voiced by Weird Al Yankovic, who does a great job with it. Part of an ongoing side story in the show involves two time travelers, who see a lot of clocks in the timestream. One of them says the clocks was probably someone’s idea of a joke. I don’t want to spoil it, because it’s fun to see how it all plays out, but if you just want to know without watching, click here and look for “Floating Clocks” (which is a common trope for showing that time travel is happening, and here they explain it… kind of). Or, if you want to see just that clip: Clocks in the timestream. (It’s a weird clip to start with though, because most episodes are more realistic and don’t involve alien pistachios.) There’s another time travel paradox in this episode involving a letter someone put in the past for their future self. (Think about that one.) There’s also a peach paradox in the show, and there’s a video clip of it on that page.

Anyway, that’s a lot of rambling about time travel, but you also got a show recommendation. I think it’s laugh-out-loud funny, and my kids like it, too. (It was created by the same guys who created Phineas and Ferb, which is another great show I recommend.)

you are the author of your life, so what’s next?

I’ve recently been thinking about writing short stories, and I also recently wrote about eating cookies to make your day better, and I combined those thoughts for the perspective of how you are the author of your own life.

Imagine your life as a story — which it is, except no one is writing it all down. Humans have used stories to remember history for as long as there has been history. You summarize your day into stories based on expectations and your worldview, some of it subconsciously, but it happens.

Now consider your day, maybe it’s a less-than-pleasant day. You wouldn’t think of it in short story form, but for the sake of this exercise, let’s try it:

Burford was late to work due to bad drivers and a traffic jam, and his boss gave him a glare as he walked in, so he wondered if that will affect his reputation and future raises. His boss doesn’t seem to recognize his value to the company. He did his daily work the best he could, but got sleepy in the afternoon because he didn’t get enough sleep last night. His lunch was boring. Leaving work, he was frustrated because there’s so much to do and there’s simply not enough time for it all. He sighed as he got into his old car that he would like to replace but can’t afford to. He was glad that work was through, but not excited about the rest of the evening.

It hasn’t been a great day for poor Burford. But what happens next? Does he let the rest of the day be “blah” or frustrating? Or does he change the script? What happens next hasn’t been written yet. There might be some required activities to do later, but what can he do to make his day better?

So many of us get into a routine with our daily habits and just let life happen to us. But you are the author of your life. What can you do to make your day better? Eat cookies. Drink sweet tea. Get outside to walk or play a sport. Listen to your favorite songs. Read something funny. (You could subscribe to this blog if you haven’t already). 🙂 Sit down to do absolutely nothing for a few minutes to clear your mind and relax. Text a friend who is funny and/or encouraging. Listen to a podcast about self-improvement. Pray. Whatever it is, there are options you can do to make your day better. And wherever you are right now, you get to write the rest of today’s chapter. What will happen?

Being outdoors in nature helps. Studies have shown that even just a couple of breaks in nature per week affects your mood the whole week. Take some time to be alone with your thoughts and be present where you are, with no distractions. Ignore your phone for 30 minutes.

When you’ve just got to dance…

When was the last time you heard music that made you dance? I don’t mean when you’ve got ants in your pants and you need to dance. Nor do I mean when you have squirrels in your pants. (Side note: If you can name both of those references without an online search, then I’ll give you 50 coolness points right now. [BTW, that’s a lot.] If you know just one of them, I’ll give you 20. I figure it’s a rare person who understands two generations of coolness. Most people only find one generations worth, although some find none. Oh, and if you have to search and you can stay focused enough to find both and still leave a comment, I’ll give you 10. I figure that’s somewhat rare too, given short attention spans these days, plus when you search the internet for cool stuff, it’s easy to follow a rabbit trail and forget where you started.) [Ed. note: That’s probably not a side note if it’s longer than the main text.]

Back to music… When was the last time you heard music that was so interesting to you that you started dancing? If the answer is not today, then perhaps you should find some. Life is too short for boring music. (Disclaimer: I’m not implying that music which doesn’t make you dance is necessarily boring — certainly not true. However, it is good to dance and feel good, so I recommend listening to music that makes you feel good on a regular basis.) This concept can apply to music from many genres: funk (of course*), jazz, hip-hop, rock, pop, country, heavy metal, classical, techno, house, bluegrass, electro-swing (naturally), etc. That may seem strange to you, since many people listen to primarily just one genre of music, but I’ve danced to all of those, so it’s definitely possible. (No, there’s no video of this. No one wants to see that. It’s for my enjoyment. And my kids dance with me sometimes, too.)

* You could say “of course” to any of them, particularly your favorite genre, but I mentioned it because just today, while doing dishes, I heard a song so funky I just had to get my groove on. If you know, you know. I was playing music while doing dishes because I really dislike washing dishes, but music makes the experience better. And I have my own playlist, set to shuffle, so it’s music that will help me stay upbeat and happy. I sometimes use this playlist while walking and exercising. And I also use it when I’m cooking something that takes a long time, like chili. In fact, just the other day I played a song in my truck that my son said, “That’s chili-making music.” I’ve never heard that before, but makes sense in this context. He had that association with it. And he helps me make chili sometimes, and he dances to the music while making chili, so he knows. Sometimes his feet start moving like he’s James Brown. (Hey, that’s a hint to not forget the coolness challenge in the first paragraph.)

So if your day could use more awesomeness, pull up some of your favorite songs to listen to when you get a chance. Why not make your day more awesome? (If you never listen to songs that make you want to dance, why not try it? Find some. Search for playlists about dancing, or ask friends for suggestions. I suspect everyone could find some songs that make them want to dance, and you need this in your life. Trust me, it’s a good time, and it’s worth the effort to find. Make your day more awesome!)

how to calculate the heat index

Have you ever wondered what the formula is to determine the heat index? You might be surprised…

Heat Index = -42.379 + 2.04901523T + 10.14333127R – 0.22475541TR – 6.83783×10-3T2 – 5.481717×10-2R2 + 1.22874×10-3T2R + 8.5282×10-4TR2 – 1.99×10-6T2R2

Who knew it was that complicated? If you want a full explanation of all those variables, go here (if you dare): It’s Not the Heat, It’s the Humidity. There are a lot of assumptions built into that equation. Basically, the heat index is different for everyone. That formula is based on an average of someone who is 5’7″ and weighs 147 pounds. The equation even accounts for how much clothes coverage you have — it assumes 84% based on “long trousers and short-sleeved shirt”. Trousers? I don’t wear trousers… I’m not British!

There should be a separate heat index for the South. On the worst of days, we don’t need a number — it should just say “STAY INSIDE!”. Because there’s days where you step out the door and you’re instantly sweating. I don’t know how that’s possible, but it’s a thing. When you can feel your skin start to burn within seconds, it’s just not safe. On those days, just stay inside.
